Our ex-batts. free range in the garden when we are at home to supervise them. I have just found a dead hen, still warm, in the middle of the drive, but behind gates. There are no feathers scattered around but the head and neck are completely missing - as if it had been sliced off - and there is no blood spilt. We didn't hear any commotion either. Any ideas what has kiiled this poor hen, which was a very healthy, friendly bird (she used to try and come into the kitchen and shared food with the dogs)!
